Abstract

UN METODO PARA TRATAR AGUA DE ALIMENTACION CON UNA MEMBRANA DE OSMOSIS INVERSA (OI) Y REDUCIR LA TENDENCIA DE LA MEMBRANA DE OI A ENSUCIARSE DEBIDO AL ALUMINIO EN EL AGUA DE ALIMENTACION O AGREGADO COMO PARTE DE UN PRE-TRATAMIENTO, QUE COMPRENDE: MEZCLAR UN COAGULANTE DE SAL DE ALUMINIO CON EL AGUA DE ALIMENTACION PARA FORMAR EL AGUA DE ALIMENTACION Y PRECIPITAR LOS PRECIPITANTES A BASE DE HIDROXIDO DE ALUMINIO DEL AGUA DE ALIMENTACION; DIRIGIR EL AGUA DE ALIMENTACION A UNA UNIDAD DE SEPARACION POR MEMBRANA DE MICROFILTRACION O ULTRAFILTRACION Y PRODUCIR UNA CORRIENTE DE PERMEADO Y UNA CORRIENTE DE RECHAZO DONDE LA CORRIENTE DE RECHAZO INCLUYE LOS PRECIPITANTES A BASE DE HIDROXIDO DE ALUMINIO; DIRIGIR LA CORRIENTE DE PERMEADO A LA MEMBRANA DE OI Y FILTRAR LA CORRIENTE DE PERMEADO PARA PRODUCIR UNA CORRIENTE DE PERMEADO Y UNA CORRIENTE DE RECHAZO; Y CONTROLAR LA CONCENTRACION DE ALUMINIO EN EL PERMEADO HACIA LA MEMBRANA DE OI CONTROLANDO EL TIEMPO DE RESIDENCIA HIDRAULICO DEL AGUA DE ALIMENTACION COAGULADA PARA EVITAR LA RESOLUBILIZACION DEL ALUMINIO.A METHOD TO TREAT FOOD WATER WITH A REVERSE OSMOSIS MEMBRANE (OI) AND REDUCE THE TREND OF THE OI MEMBRANE TO BE SMOOTED DUE TO ALUMINUM IN THE FOOD WATER OR ADDED AS PART OF A PRE-TREATMENT, WHICH INCLUDES: ALUMINUM SALT COAGULANT WITH FOOD WATER TO FORM FOOD WATER AND PRECIPITATE FOOD WATER ALUMINUM HYDROXIDE BASED PRECIPITANTS; DIRECT THE FEEDING WATER TO A MICROFILTRATION OR ULTRAFILTRATION MEMBRANE SEPARATION UNIT AND PRODUCE A PERMEATED CURRENT AND A REJECTION CURRENT WHERE THE REJECTION CURRENT INCLUDES HYDROX BASED PRECIPITANTS; DIRECT THE PERMEATED CURRENT TO THE OI MEMBRANE AND FILTER THE PERMEATED CURRENT TO PRODUCE A PERMEATED CURRENT AND A REJECT CURRENT; AND CONTROLLING THE CONCENTRATION OF ALUMINUM IN THE PERMEATE TOWARDS THE MEMBRANE OF OI CONTROLLING THE TIME OF HYDRAULIC RESIDENCE OF THE COAGULATED FOOD WATER TO AVOID RESOLUBILIZATION OF THE ALUMINUM.
